Easy Scarthgap print setup broken

This came as a surprise. My daily workhorse PC has a Brother HL2040 laser printer connected via USB. Printing works, but I have not for quite some time tested setting up a new printer.  I have just updated the Easy Scarthgap installation on the PC, with an already-setup CUPS connection with the printer.

Until today. Running the CUPS web interface on a pristine EasyOS Scarthgap 6.4.5, choosing to add a printer, and it is listed:

So far OK. Click on "Continue" and this is what is supposed to be the next window:

However, this is what appears:

...that window should not be appearing, as a local printer was selected by radiobutton.

I booted Easy Daedalus 6.4.1, and printer setup works. Hmmm.

So, I tested older versions of Easy Scarthgap, pristine installs to USB-stick. Tried 6.3.1; fail. Then 6.2; fail.

Then Easy Scarthgap 6.0.4; success.

Right now, I have no idea what is causing the problem. It isn't kernel version, have eliminated that.

How does that saying go; "It never rains but it pours"

Oh well, will try and track down the cause. Maybe a hint: see the above photos, the window that works shows CUPS 2.4.7, the bad one is 2.4.10.
